Ruby RubyGems
RubyGems is a bundle administrator for Ruby that gives a standard organization to conveying Ruby projects and libraries, just as an instrument for overseeing bundle establishment.
RubyGems is intended to effectively deal with the instruments introduced by the diamond and the servers used to convey the pearl. This is like well-suited get under Ubuntu, yum for Centos, and pip for Python.
RubyGems was made in November 2003 and turned out to be a piece of the Ruby standard library from Ruby 1.9.
If your Ruby is lower than variant 1.9, you can likewise introduce it manually:

Update the RubyGems command:
$ jewel update - - System # requires manager or root user

So you won't react when you experience diamond introduce rack or pack introduce for quite a while. You can utilize diamond introduce rails - V to see the execution procedure.
So we can alter it to Taobao download source: http://ruby.taobao.org/First, check the current source:
$ pearl sources -l *** CURRENT SOURCES *** Https://rubygems.org/
Next, expel https://rubygems.org/and include the Taobao download source http://ruby.taobao.org/.
$ pearl sources - - Remove https://rubygems.org/ $ pearl sources -a https://ruby.taobao.org/ $ pearl sources -l *** CURRENT SOURCES *** Https://ruby.taobao.org # Make beyond any doubt that just ruby.taobao.org $ diamond introduce rails
If you use Gemfile and Bundle (for instance: Rails project)
You can utilize the pack's jewel source code to reflect directions.
$ group config mirror. Https://rubygems.org https://ruby.taobao.org
This way you don't need to change the wellspring of your Gemfile.
